Pneumonite actínica e bronquiolite obliterante com pneumonia em organização pós-radioterapia / Radiation pneumonitis and bronchiolitis obliterans organizing pneumonia (BOOP) after radiotherapy: case report

A radioterapia torácica, utilizada para o tratamento de câncer de mama, pode causar lesões pulmonares como pneumonite actínica e bronquiolite obliterante com pneumonia em organização (BOOP) ou também conhecida como pneumonia em organização, sendo esta mais incomum. Isso pode ocorrer mesmo se realizada em doses dentro do limite de tolerância aceitável para a segurança do paciente.Este relato de caso descreve a história de uma paciente que foi submetida a tratamento radioterápico após a retirada cirúrgica de um tumor maligno de mama e que duas semanas após o término do tratamento apresentou quadro clínico e de imagem de pneumonite actínica. Concomitantemente foi diagnosticada com BOOP, confirmado por tomografia computadorizada de tórax e biópsia transbrônquica. Foi tratada com corticoterapia pelo período de três meses e apresentou melhora clínica e radiológica.Houve, entretanto, dois episódios de recidiva dos sintomas de BOOP após o fim do tratamento. Realizou-se, então, pulsoterapia mensal com metilprednisolona por 12 meses. Um ano após o fim do tratamento se apresenta assintomática e sem uso de medicamento algum. Estudos de imagem demonstraram apenas lesão residual actínica no lobo superior esquerdo.Concluímos que após um tratamento de radioterapia torácica, devemos ficar atentos à ocorrência de lesões pulmonares associadas. E especialmente para casos de BOOP há a necessidade de um tratamento de imunossupressão pelo período mínimo de um ano, pois melhoras iniciais e rápidas induzem o médico a parar o tratamento de forma precipitada, podendo levar a recidivas...

Pneumonia em organização secundária ao uso de abciximab: relato de caso / Secondary organizing pneumonia after Abciximab use: case report

Relata-se o caso de paciente octogenária, com infarto agudo do miocárdio (IAM) em evolução, que desenvolveu quadro inflamatório pulmonar agudo, compatível com diagnóstico de pneumonia em organização secundária ao uso de abciximab intracoronariano, em angioplastia percutânea coronariana (APC). Esse diagnóstico foi firmado por meio de alterações clínicas, radiográficas e tomográficas típicas e pela regressão dessas alterações após terapia com corticosteroide.

This report presents the case of an octogenarian female patient with acute myocardial infarction who developed an acute inflammatory pulmonary condition compatible with a diagnosis of secondary organizing pneumonia after intracoronary abciximab during percutaneous coronary angioplasty. This diagnosis was grounded on typical clinical, radiographic and tomographic alterations and the regression of these alterations after corticoid treatment.

Temozolomide-Associated Bronchiolitis Obliterans Organizing Pneumonia Successfully Treated with High-Dose Corticosteroid

Temozolomide is an oral alkylating agent with clinical activity against glioblastoma multiforme (GM). It is generally well-tolerated and has few pulmonary side effects. We report a case of temozolomide-associated brochiolitis obliterans organizing pneumonia (BOOP) requiring very high-dose corticosteroid treatment. A 56-yr-old woman presented with a 2-week history of exertional dyspnea. For the treatment of GM diagnosed 4 months previously, she had undergone surgery followed by chemoradiotherapy, and then planned adjuvant chemotherapy with temozolomide. After the 1st cycle, progressive dyspnea was gradually developed. Chest radiograph showed diffuse patchy peribronchovascular ground-glass opacities in both lungs. Conventional dose of methylprednisolone (1 mg/kg/day) was begun for the possibility of BOOP. Although transbronchial lung biopsy findings were compatible with BOOP, the patient's clinical course was more aggravated until hospital day 5. After the dose of methylprednisolone was increased (500 mg/day for 5 days) radiologic findings were improved dramatically.

Bronchiolitis Obliterans with Organizing Pneumonia (BOOP) in a Patient with Rheumatoid Arthritis / 대한류마티스학회지

Interstitial lung disease (ILD) is one of the common extra-articular manifestations of rheumatoid arthritis (RA). Bronchiolitis obliterans with organizing pneumonia (BOOP) is one type of ILD, and this is characterized by the proliferation of granulation tissue in the bronchioles, alveolar ducts and some alveoli and interstitial infiltration by chronic inflammatory cells. It develops as a manifestation of RA or as a side effect of anti-rheumatic drugs in patients with RA. We experienced a 41-year-old female patient with RA who developed BOOP during the treatment with methotrexate and bucillamine. She presented with cough and sputum for several months and pleuritic chest pain for one week. The chest radiograph showed bilateral multifocal consolidations. She received thoracoscopic biopsy and her pulmonary infiltrations resolved after the treatment with corticosteroid.

Neumonía en Organización: revisión del tema y presentación de 4 casos / Organizing pneumonia: revision of the topic and presentation of 4 cases

Se hace una revisión de las Neumonías en Organización según el concepto actual de las mismas, su nomenclatura diferente de las usadas previamente (BOOP), y las características clínicas, clasificación etiológica, alteraciones funcionales y anormalidades en las imágenes. Se comentan 4 casos clínicos de interés, dos con confirmación biópsica, y dos debidos a toxicidad por amiodarona. Se describe la afectación clínica, funcional y radiológica de los casos y se enfatiza un paciente con alteración tomográfica inusual y otro con evolución fibrótica progresiva asociado a artritis reumatoidea que se hizo aparente un año después del COP y coincidió con una exacerbación tardía del mismo.

Organizing pneumonias are reviewed according to the new approach from ATS/ERS statement. Most frecuent clinical patterns, image studies and functional alterations are commented on. Four clinical cases are described, two with pathological confirmation and two other amiodarone related. Unusual HRTC presentation is remarked in one case and another one due to rheumatoid arthritis, with pulmonary alteration preceding in one year rheumatic manifestations and relapsing one year later simultaneously with clinical and serologic rheumatoid arthritis.

Two Cases of Bronchiolitis Obliterans Organizing Pneumonia treated with Steroid and Cyclosporine therapy / 결핵및호흡기질환

A rapid response to corticosteroid treatment and a generally favourable outcome are characteristic features of BOOP (Bronchiolitis obliterans organizing pneumonia). However, with increasing experience of the clinical spectrum of this disease, it is now recognized that some patients are refractory to steroid, which is associated with a poor prognosis. Here, two cases of BOOP initially treated with predinisone and antibiotics without effects, but subsequently responded to secondary cyclosporine treatment, are reported.

A case of bronchiolitis obliterans organizing pneumonia in patient with systemic lupus erythematosus / 대한내과학회지

Pleuropulmonary manifestations of systemic lupus erythematosus (SLE) are protean and include pleuritis, pulmonary nodule, chronic interstitial pneumonitis, pulmonary hypertension, pulmonary embolism, alveolar hemorrhage, bronchiolitis obliterans (with or without organizing pneumonia), and opportunistic pulmonary infections. Although bronchiolitis obliterans organizing pneumonia (BOOP) has been associated with several connective tissue disorders, there are rare repots of BOOP in patients with SLE. We present a patient with SLE who complained cough and exercise induced dyspnea. Simple chest radiography and high resolution computed tomography (HRCT) of lung were consistent with BOOP and thoracoscopic lung biopsy showed BOOP. Clinical symptoms and radiographic findings were improved after treatment with methylprednisolone pulse and intravenous cyclophosphamide pulse therapy.

Recidiva en bronquiolitis obliterante con neumonía en organización: BOOP / Relapsein bronchholitis obliterans organizing pneumonia: boop

Although relapses are frequent in bronchiolitis obliterans organizing pneumonia (BOOP), there is scant information regarding the causes underlying its occurrence. We report a 63 year old woman with clinical and radiological features compatible with BOOP. No underlying cause was identified so she was thought to have cryptogenic BOOP or cryptogenic organizing pneumonia (COP). A transbronchial lung biopsy demonstrated chronic organizing pneumonia and features of proliferative bronchiolitis. She was successfully treated with prednisone. On the eighth month of steroid therapy, while tapering the dose, she begun with cough and dyspnea and developed new lung infiltrates on the chest x-ray film. The infiltrates cleared rapidly after increasing the dose of steroids. We discuss the possible causes of relapse in BOOP and its relation to steroid therapy.

Las recaídas son frecuentes en la bronquiolitis obliterante con neumonía en organización (BOOP), sin embargo, existe poca información con respecto a su causa. Se presenta el caso de una mujer de 63 años con un cuadro clínico radiológico compatible con BOOP. No se identificó una causa subyacente por lo que se planteó el diagnóstico de neumonía en organización criptogénica o COP. Se realizaron biopsias transbronquiales que demostraron una neumonía crónica organizada y bronquiolitis proliferativa. Se trató con prednisona con buena respuesta. Al octavo mes de tratamiento, mientras se disminuía la dosis de esteroides, comenzó con disnea y tos y aparición de nuevas opacidades pulmonares radiológicos, las que regresaron rápidamente al aumentar la dosis de esteroides. Discutimos las causas posibles de la recidiva de esta patología y su relación con la disminución de la dosis de esteroides.

A Case of the Bleomycin-Induced Bronchiolitis Obliterans Organizing Pneumonia / 결핵

A 34-year-old man was admitted to our hospital due to fever and cough. He received the combination anti-cancer chemotherapy for testicular tumor, including bleomycin. The chest X-ray showed consolidation and ground glass opacity on the right upper lobe and subpleural areas of other lobes. This condition was initially misdiagnosed as a pneumonia, but consolidation did not disappear after antibiotics treatment. We performed transbronchial lung biopsy and bleomycin induced pulmonary toxicity was confirmed. The bleomycin induced lung injury is the most common chemotherapeutically induced pulmonary disease. Bleomycin induced Bronchiolitis Obliterans Organizing Pneumonia(BOOP) is less common than interstitial pneumonitis and respond well to corticosteroid treatment.

A Case of carbamazepine induced bronchiolitis obliterans organizing pneumonia / 결핵

BOOP(Bronchiolitis Obliterans Organizing Pneumonia) is an inflammatory reaction that follows damage to the bronchiolar epithelium of the small conducting airways. BOOP is characterized by the pathologic finding of excessive proliferation of granulation tissue within the respiratory bronchioles, alveolar duct and spaces, accompanied by organizing pneumonia. BOOP may result from diverse causes such as toxic fumes, connective tissue disorders, infections, organ transplantation and drugs or appear idiopathically. Drug induced BOOP has been described in association with acebutolol, amiodarone, cephalosporin, bleomycine, tryptophan, gold salts, barbiturates, sulfasalazine, and carbamazepine. Carbamazepine is an iminostilbene derivative that is used as both and anticonvulasnt and pain reliever for pains associated with trigeminal neuralgia. It is structually related to the tricyclic antidepressants. To our knowledge, there have been no previously reported case that has described development of BOOP during carbamazepine treatment in Korea, and only two cases have been reported in the world. We report a case of carbamazepine-induce BOOP with a brief review of literature.

A Case of Polymyositis Preceded by Bronchiolitis Obliterans with Organizing Pneumonia(BOOP) / 대한내과학회지

Polymyositis is a inflammatory connective tissue disorder of unknown etiology involving predominantly skeletal muscle, characterized by progressive symmetrical proximal muscle weakness, elevated serum muscle associated enzymes, characteristic pattern of electromyography, mononuclear cell infiltration in muscle, and skin lesions in dermatomyositis. Interstitial lung disease in association with polymyositis occurs in 5~10% of cases, with generally a poor prognosis and its subclassification may be a useful predictor of survival. We have experienced a case of polymyositis associated with bronchiolitis obliterans with organizing pneumonia (BOOP). The patient was a 54 year-old woman presented with progressive weakness of both lower extremity and weight loss during 6 months. She had been diagnosed as BOOP by transbronchial lung biopsy 2 years ago. She had typical symptoms, physical signs and elevated serum muscle associated enzymes with characteristic findings of myositis on electromyography and muscle biopsy. Her chest roentgenogram showed slightly improvement of underlying BOOP as compared with that of 2 years ago. Because wound infection was developed at the skin biopsy site, steroid was not used. She finally expired due to sudden cardiopulmonary arrest.

A Case of Pneumocystis Carinii Pneumonia with Histopathologic Finding of Bronchiolitis Obliterans with Organizing Pneumonia in Patient with AIDS / 결핵

PCP remains the leading cause of deaths in patients with AIDS. As familiarity with PCP increases, atypical manifestations of the diseases are being recognized with greater frequency. There are following "atypical" manifestations of PCP; 1) interstitial lung response that include diffuse alveolar damage, bronchiolitis obliterance, interstitial fibrosis, and lymphoplasmocytic infiltrate 2) striking localized process frequently exhibiting granulomatous features 3) extensive necrosis & cavitation 4) extrapulmonary dissemination of the disease. A wide variety of pathologic manifestations may occur in PCP in human immunodeficiency virus- infected patienst and that atypical features should be sought in lung biopsies from patients at risk for PCP. We had experienced a case of PCP, which presented with severe hypoxia, progressive dyspnea and fine crackles. It was diagnosed as PCP in AIDS with manifestation of BOOP by open lung biopsy and showed good response to Bactrim & corticosteroid therapy.

2 cases of idiopathic BOOP associated with rare radiologic finding / 결핵

Idiopathic bronchiolitis obliterans with organizing pneumonia (BOOP) is a specific clinicopathologic syndrome characterized by a pneumonia-like illness, with excessive proliferation of granulation tissue within bronchioles, alveolar ducts and alveoli. The changes are most numerous in alveolar ducts. The presence of intraluminal tufts of organizing connective tissue in alveolar ducts and more distal airspaces has been termed organizing pneumonia The radiologic manifestations are distinctive with bilateral, diffuse alveolar opacities predominantly in the subpleural and lower lung zone. Patchy migratory pneumonic foci or solely nodular infiltrates are rarely present in BOOP. BOOP is a diagnosis of importance because of its dramatic response to steroids.

Constrictive Bronchiolitis Accompanied By Non-Hodgkin's Lymphoma / 결핵

Constrictive bronchiolitis, one of small airway diseases, is very rare and occupies one of the two arms of bronchiolitis obliterans together with proliferative bronchiolitis. Proliferative bronchiolitis, presenting the prototype with bronchiolitis obliterans with organizing pneumonia(BOOP), can be easily taken into diagnostic consideration in terms of relatively rapid clinical course and radiologic presentation as if atypical pneumonia with interstitial and alveolar infiltrations. Meanwhile constrictive bronchiolitis is not only very rare but also easily overlooked as chronic obstructive pulmonary diseases such as emphysema, because it usually shows normal chest radiographic finding and obstructive pattern in pulmonary function test. In the aspects of the reponse to treatment, proliferative bronchiolitis showed dramatic response to the corticosteroid while constrictive bronchiolitis is intractable, which is easily explained on the basis of the pathologic characteristics of cicartrical replacement of bronchiolar walls. The bronchiolitis, both proliferative and constrictive, can be associated with diverse conditions such as inhalational injury, postinfectious process, drug or chemical induced reactions, connective tissue diseases, and organ trasplantation. And there is idiopathic type which has no associated condition. There is one explanation that both types of bronchiolitis lie on the same disease spectrum because the different disease pattern can be evoked from the same etiology. In contrast, another explanation is suggested that both types of bronchiolitis are one of nonspecific tissue reaction rather than a disease specific histologic finding because the various types of causes can provoke the same histologic findings. These dilemma remains for further investigation. With literature investigation, the authors report a case of constrictive bronchiolitis proven by open lung biopsy in 47 year old female who was diagnosed as non-Hodgkin's lymphoma and simultaneously had relatively rapid progression of airflow obstruction and showed negative radiographic finding without the risk factors for the development of chronic obstructive lung disease. We consider it as idiopathic because we could not find any relationship between constrictive bronchiolitis and non-Hodgkin's lymphoma on the literature search and it requires further investigation.
